PRECOMPENSATION METHOD AND DEVICE FOR ADJUSTING LUMINOSITY AND CHROMATICITY OF PANEL

摘要

Provided are a precompensation method and device for adjusting the luminosity and chromaticity of a panel. The method comprises: step 10, adjusting the gamma voltage of a first subpixel so that the grayscale luminosity of the first subpixel is Lum_T'; step 20, adjusting the gamma voltage of a second subpixel so that the grayscale chromaticity of the second subpixel is y_T'; step 30, adjusting the gamma voltage of a third subpixel so that the grayscale chromaticity of the third subpixel is x_T; and step 40, determining whether a standard is met, if the standard is met, stopping the adjustment, and if the standard is not met, returning to step 10 to restart the adjustment. The precompensation method and device for adjusting luminosity and chromaticity of a panel introduce a precompensation correction mechanism. This avoids repeated adjustment, shortens adjustment time, improves efficiency, and effectively prevents oscillations in the adjustment process, namely the situation in which the adjustment never converges; a linear estimation iteration mode is further introduced to adjust the gamma voltage, improving the efficiency of adjusting the gamma voltage.
